Although there is a fastener with three consecutive long holes for inserting the tape, it has a drawback that it takes time to adjust the length of the tape or the string. The present invention provides a fastener which is highly decorative and easy to use. [Structure] A casing 1 having a hollow interior and a U-shaped spring member 2 housed inside are provided with insertion holes 3 such as rubber cords on opposite surfaces of the casing. Also has an insertion hole 4 such as a rubber cord, and the end portion 2a of the U-shaped spring member slightly projects from the side surface of the casing.
When the end portion is pushed inward of the casing, the insertion hole 3,

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mask, a rubber cord such as goggles, and a fastener suitable for adjusting the cord or tape length.

[0002]

[Prior art]

 A sun can is generally known as a stopper which is generally used for adjusting the length of a rubber cord or the like. In addition, there is a fastener with three consecutive long holes for inserting the tape, which is similar to the sun.

[0003]

[Problems to be solved by the device]

 From the standpoint of decorativeness, there is room for improvement in the sun cans that have been conventionally used. In addition, the three long holes have a drawback that it takes time to adjust the length of the tape or the cord.

[0004]

[Means for Solving the Problems]

 The stopper such as a rubber cord according to the present invention comprises a casing 1 having a hollow inside and a U-shaped spring member 2 housed in the casing. The U-shaped spring member also has an insertion hole 4 such as a rubber cord, and the end 2a of the U-shaped spring member slightly protrudes from the side surface of the casing, and the end is pushed inward in the casing. At this time, the insertion holes 3 and 4 are communicated with each other, and the insertion holes 3 and 4 are assembled in such a manner that the insertion holes 3 and 4 are always stepped when the end 2a of the U-shaped spring member is projected.

[0005]

[Action]

 Pushing the end 2a of the U-shaped spring material that protrudes from the side of the casing into the casing will allow the insertion holes 3 and 4 to communicate with each other, so you can pass a rubber cord or the like, adjust the position, and further adjust the length of the ring difference. . When the end portion 2a of the U-shaped spring member is projected, the insertion holes 3 and 4 are always out of step so that the cord can be fixed. When there is one insertion hole, the position of the stopper can be adjusted, and when there are two insertion holes, the length of the ring difference such as rubber cord can be adjusted. Therefore, a mask can be fitted to the face.

【Example】

 1 and 2 show a first embodiment of the present invention, FIG. 1 (a) is a partially cutaway front view, and FIG. 1 (b) is a side view thereof. FIG. 2 is a perspective view before assembly. This example is a stopper composed of two members, a circular casing 1 having a hollow inside and a U-shaped spring member 2 housed inside. The casing 1 has an insertion hole 1a for the U-shaped spring material 2 on the upper surface and projection holes 1b, 1b for the ends 2a of the U-shaped spring material on both sides. Further, the casing 1 is provided with insertion holes 3 such as rubber cords on the opposite surfaces. At both ends of the U-shaped spring material 2, there are also insertion holes 4 such as rubber cords. The both ends are protruding so that they can be pushed with fingers. The insertion hole 3 of the casing 1 and the insertion hole 4 of the U-shaped spring member 2 communicate with each other when both ends 2a, 2a of the U-shaped spring member 2 are pushed inwardly of the casing. Both ends of the U-shaped spring member are assembled so that the insertion holes 3 and 4 are always in a stepped state when both ends 2a and 2a are projected.

3 and 4 show a second embodiment, FIG. 3 (a) is a partially cutaway front view, and FIG. 3 (b) is a side view thereof. 4A is a front view of only the casing 1, FIG. 4B is a sectional view taken along the line AA in FIG. 4A, and FIG. 4C is a sectional view taken along the line BB. In this example, the casing 1 is formed by assembling two members 1a and 1b. It is the fitting protrusions provided on each of the two members that maintain the space between them and keep the inside hollow. One of them is inserted into the other fitting protrusion and fixed by fitting. . The casing 1 has an insertion hole 3 for a rubber cord or the like, and the both ends 2a, 2a of the U-shaped spring member 2 also have the insertion holes 4, 4 for a rubber cord or the like as in the above-described embodiment.

FIGS. 5 and 6 are third and fourth embodiments. FIG. 5 is a perspective view of a third embodiment of the stopper of the present invention, and FIG. 6 is an exploded perspective view of the fourth embodiment. The casing 1 is provided with an insertion hole 1a for a lock member 5 provided with a U-shaped spring material 6 and insertion holes 3 such as rubber cords on both side surfaces on opposite sides, respectively. The lock member 5 has one insertion hole 4 such as a rubber cord. The head portion 5a of the lock member is flat so that it can be pushed by a finger. The insertion hole 3 of the casing 1 and the insertion hole 4 of the lock member 5 are communicated with each other when the head 5a of the lock member 5 is pushed inward of the casing, and the head 5a of the lock member 5 is connected. When the projecting state is, these insertion holes 3 and 4 have different steps. This allows the position of the stopper to be adjusted. In this example, the U-shaped spring member 6 is provided to bias the lock member, but a U-shaped spring member or a spiral spring or a jagged plastic piece may be used.

[0009]

[Effect of device]

 According to the present invention, it is possible to provide a fastener which is highly decorative and easy to use. Also, since it can be manufactured by plastic injection molding, it can be supplied at low cost.
